Intelligent Plastic Changes Color To Indicate Stale Food

Scientists at the University of Strathclyde in Glasgow have developed a smart plastic that would indicate if the food packaged in it is spoiled or not. The plastic, which can be integrated in the packaging itself, changes color when it senses the food going bad because of it being left for too long or not being refrigerated. What’s more, the new material would be cheaper than the currently used labels present in atmosphere packaging that indicate freshness, making it a viable solution to prevent the risk of consuming stale food.
